Can you clarify this comment please?

If I correctly understood you then your approach was to develop the function at a fixed point and then regularly iterate the function there and then define tetration as . It quite looks (as I numerically verified in this post) as if this yields the same result as Andrew's approach (of course only for bases because only there exists a real fixed point at all. The solution can also only applied to the lower fixed point (of the two fixed points of for ), because the other fixed point is not reachable from 1.)
